Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83580, here are decompositions:

17 + 83563 = 83580
19 + 83561 = 83580
23 + 83557 = 83580
43 + 83537 = 83580
83 + 83497 = 83580
103 + 83477 = 83580
109 + 83471 = 83580
131 + 83449 = 83580

Showing the first eight; more decompositions exist.
